The sorting mechanism 31 removes foreign substances mixed with crops through repeated reciprocating movement. The first tuyere (61) can generate wind toward the lower side of the sorting mechanism (31). Accordingly, the first tuyere 61 can remove foreign substances mixed with crops that have passed through the sorting mechanism 31 using wind. In this case, foreign matter that is lighter than the grains that passed through the sorting mechanism 31 may be removed by the wind generated by the first tuyere 61. Grains that have passed through the sorting mechanism 31 may fall without being removed by the wind generated by the first tuyere 61 and then be conveyed through a separate conveyance mechanism.

The transmission mechanism 62 adjusts the rotation speed of the first tuyere blade 611 according to the moisture content measured by the measuring unit 5.

In this case, the moving mechanisms 632 can move the blocking members 631 individually. When the air volume control mechanism 63 includes a plurality of the blocking members 631, the air volume control mechanism 63 may include an interlocking mechanism (not shown) connecting the blocking members 631. The moving mechanism 632 can simultaneously move the covering members 631 by moving the linking mechanism.

The moving mechanism 632 can move the blocking member 631 so that the area that the blocking member 631 covers the inlet 613 decreases as the moisture content measured by the measuring unit 5 increases. As the area where the blocking member 631 covers the intake port 613 decreases, the flow rate of air sucked into the first tuyere 61 may increase. Accordingly, the wind volume control mechanism 63 can increase the volume of wind generated by the first tuyere 61 toward the crops. Therefore, the blower 6 according to the second embodiment can smoothly remove foreign substances whose weight has increased due to increased moisture by increasing the air volume using the air volume control mechanism 63.

The combine is characterized in that the measuring part (5) is coupled to the lower surface (412) of the transport body (41) so as to be located on the lower side of the transport mechanism (42). According to clause 8,
The transport body 41 includes a first side 413 coupled to one end of the lower surface 412, and a second side 414 coupled to the other end of the lower surface 412,
The measuring unit 5 is coupled to the lower surface 412 of the transport body 41 so that the distance from each of the first side 413 and the second side 414 is the same. A combine that does. A harvesting unit (2) for performing the harvesting operation of harvesting crops;
A threshing unit (3) for performing the threshing operation of threshing crops;
A transport unit (4) for carrying out a transport operation of transporting the crops harvested by the reaping unit (2) to the threshing unit (3);
A grain storage unit (8) for storing grain on which the threshing operation was performed;
A measuring unit (5) coupled to the grain storage unit (8) and measuring the amount of moisture contained in the grain stored in the grain storage unit (8);
A blowing unit (6) coupled to the threshing unit (3) and adjusting the air volume for the crops transported to the threshing unit (3) according to the moisture content measured by the measuring unit (5); and
A control unit (7) that controls the operation of the blowing unit (6)
Including,
The blowing unit (6) is:
A first winnower (61) that blows wind toward the crops transported to the threshing unit (3); and
A second tuyere (64) that generates wind toward the crops transported to the threshing unit (3) and is disposed at a position spaced apart from the first tuyere (61).
Including,
The moisture amount measured by the measuring unit 5 is provided to the second tuyere 64,
While the first tuyere (61) always operates regardless of the moisture amount measured by the measuring unit (5), the second tuyere (64) operates selectively according to the moisture amount measured by the measuring unit (5). If the moisture amount measured by the measuring unit 5 is greater than the preset reference value, the second tuyere 64 operates to generate wind toward the crops, and if the moisture amount measured by the measuring unit 5 is less than the preset reference value, the second tuyere 64 operates to generate wind toward the crops. The second tuyere 64 stops operating,
The control unit 7 receives the moisture amount measured by the measuring unit 5 and controls whether the second tuyere 64 operates according to the moisture amount measured by the measuring unit 5. The combine.
